摘要
以海南省国营阳江农场为例,阐述了如何将GIS技术应用在橡胶园土壤样品采集上。运用ArcGIS对橡胶园土壤类型图、林段分布图等专题地图进行处理。以土壤类型和按定植年度合并的林段为依据,通过叠加分析,取其交集并以树位作为表达单元,得到全场243个采样单元,为国营农场橡胶园施肥工作的更加精准化提供参考。
GIS technology was applied in soil sampling of rubber plantations taking Yangjiang State Farm as an example. Soil map and tree stand distribution maps for the rubber plantations were delineated and processed spatially by using ArcGIS to produce their thematic maps. Units for soil types and rubber stands were overlaid with the tree task as an expression unit, based on which 243 sampling units were produced for all the rubber plantations in the state farm. These sampling units provide a reference for further preci- sion fertilization of rubber plantations in the state farm in the future.
